[vtkusers] Json object error caused by websocket.py

[Aron Helser]

Were you referring to this VTK web example?
https://www.vtk.org/Wiki/VTK/Examples/Python/Web/RemoteRenderer
This has been updated on the ParaViewWeb examples page for wslink:
https://kitware.github.io/paraviewweb/examples/RemoteRenderer.html
As you can see it is very similar.

Hope that helps,
Aron
